TROLLEY.

Specification of Letters Patent.

Patented Dec. 29, 191%.

Application filed April 28, 1914.. Serial No. 835,022.

To all whom it may concern:

Be it known that we, ROGER B. HrNroN and OsoAR KoRT, citizens of the United States, residing at Los Angeles, in the county of Los Angeles and State of Cal1fornia, have invented new and useful Improvements in Trolleys, of which the following is a specification.

The present invention relates to improvements in trolleys for vehicles deriving propelling power from overhead conductors.

In carrying out our invention we propose to provide a trolley which shall include a comparatively long roller in lieu of a grooved wheel and to provide the arms of the device with guard fingers arranged on the opposite sides of the roller, so that the liability of the conductor wire moving off of the roller in a transverse direction will be reduced, if not entirely overcome.

We also propose to provide a trolley which shall under all conditions be forced into engagement with the conductor wire, the said engagement being sufficient to provide for all irregularities or curves in the wire, but whichmay be easily and quickly lowered from such engagement when desired.

WVith the above objects in View, and others which will appear as the nature of the invention is more fully understood, the improvement resides in the construction, combination and arrangement of parts set forth in the following specification and falling within the scope of the appended claims.

The essential features of the invention involved in carrying out the objects above indicated, are necessarily susceptible of embodiment in various forms of construction without departing from the scope of the invention, but certain preferred and practical embodiments are exemplified by the accompanyingdrawings, in which Figure 1 is a side elevation of a car provided with our improved trolley, the same engaging with an overhead wire conductor. Fig. 2 is a central vertical longitudinal sectional view through the same, Fig. 3 is a section with the trolley lowered and approximately on the line w-m of Fig. 4:. Fig. 4 is a plan view of the device with the trolley in its lowered position, Fig. 5 is a transverse sectional View approximately on the line 5--5 of Fig. i, and Fig. 6 is a sectional view on the line 6.6 of Fig. 4.

Referring now to the drawings in detail, 1 designates an overhead conducting wire, 2

a car or like vehicle arranged to travel upon a track below the wire 1, and 3 our improved trolley in its entirety. The trolley 3 includes a base frame in the nature of an elongated rectangular member which is arranged longitudinally and centrally upon the top of the car or vehicle 2. The frame includes a pair of side members 4: having end connecting members 5.

Disposed centrally between the sides a of the frame and connected thereto is a pair of vertically arranged uprights These uprights are provided, at their lower ends, with a transverse spacing member or brace 7, while secured to the upper edges of the uprlghts is a spacing and bracing member in the nature of a platform 8. The uprights 6 are disposed opposite each other, as stated, and each of said arms is centrally slotted, as at 9, the said slots extendingnearly the entire length of the uprights.

The side members l of the frame between the arms 6 and one of the ends 5 of the frame are provided with elongated longitudinally extending slots 10 and arranged for longitudinal movement within the said slots 10 is a cross head 11. The cross head comprises a substantially rectangular member and has its ends projecting through the slots, while pivotally connected with the said ends are the arms or sides 12 of the conductor 13.

The arms or sides 12 are provided with transverse webs or connecting. members 1 1 and 15 respectively, the web 14 being disposed adjacent the free ends of the arms, the second web 15 being arranged a suitable distance from the pivoted ends of the sides or arms 12, and above the frameof the device.

The numeral 16 designates an anti-frictional roller which has its ends provided with trunnions or short axles 17, the same finding bearings in openings in the arms or sides 12, and the said roller is arranged within the slots 9 of the arms, and is adapted to engage with the walls provided by the said slots. The roller 16 is arranged approximately centrally of the conductor 13, and the outer or free ends of the arms or sides 12 are provided with registering openings which form journals for the trunnions or short axles 18 of a conductor roller 19.

The ends of the arms 12 are further provided with outwardly extending upwardly flared directing flanges 20 which are adapted to serve as means to assist in preventing the its wire 1 moving laterally from off of the conductor roller 19. It should here be stated that the roller 19 is of a comparatively great length, so that the car will be permitted to round curves or to engage with laterally extending bent or extending portions of the wire 1 without danger of the said wire leaving the roller 19, and as a matter of fact the conductor 13 is, in practice, of a width approximately equalingone-half of the width of thecar upon which it is arranged.

Secured upon the cross head 11 and also connected to the end 5 of the frame, opposite the: said cross head, is a pair of pressure springs 21', the said springs being of suiiici'ent strengtlr to move the conductor to bring its anti-frictional roller 16 to the top wall provided by the slots 9 in the uprights 6;

The arms or sides 12 of the conductor 13 are formed with angular extensions 22 and it is upon the ends of these extensions that thefianges 20 are'formed, and also-the conductor roller 19" is journaled in suitable bearings provided in the said angular portions. 22 of the arms of the said conductor 13. By this arrangement the portions 22 of the-conductor are arranged centrally and in a line with the vertical uprights 6 when the conductor is moved to its opposite position by the springs 21.

Centrally connected with the cross head If and extending longitudinally of the frame? and finding a bearing in an opening 23 in the brace 7 of the upright 6, is a piston rod 24, the said rod having its free end provided with a piston head 25 that works in a cylinder 26",. the said cylinder being secured between the side members of the frameupon a transversely arranged block or support 27, and connected with the cylinder, at the closed end thereof, is an air pipe 28,

i the same being connected with the air storcylinder and which is provided with a valve 3 1, which arrangement permits of a certain amount of fluid remaining in the cylinder to serve as acushion for the piston head and for adjusting the tension of the springs 21. It is,, of course, to be understood that the springs. 21 will permit of a rocking or swinging movement of the trolley or conductor when the same contacts with an obstacle in the trolley wire 1, so the trolley is at all times sustained in a yieldable condition, and in order to support the trolley when the same is. lowered. as well as to limit the movement of the said trolley in such a direction, we provide a vertically projecting member 32 which is arranged to contact with the upper web 1d between thesides or arms 12 of the conductor and so support the same when lowered.

In order to provide means whereby the frame may be easily and quickly secured upon an ordinary trolley car, we provide the tor, and also that the wiring from the conductor. to the meter ot the car may be arranged in any manner best suited, and so such. an arrangement has not been deemed necessary to illustrate.

From the above description taken in connection with the drawings, the advantages and method of operation will, it is thought, be apparent to those skilled in the art to which such invention appertains without further detailed description.

Havingthus described the invention, what we claim is:
